“Battery was DEAD after being parked for one week. Car was in residential garage (outdoor temp about 10 degrees. garage temp measured 46 degrees. Please Note: The SAME problem happened to my 2025 plug in RX and 2025 plug in NX. I doubt this is a coincidence and there are plenty of websites that indicate a significant problem.”
NHTSA complaint #11717886, filed 2026-02“Our 19-month old Lexus NX450h with under 7,000 miles on it was not driven for a week. When we went to start the vehicle this morning, the car would not unlock via the keyfob, credit card key or app. The car required AAA to open the doors and jump start it. This is a very common failure with the 12-volt battery in the Lexus NX hybrids. This could result in a motorist being left stranded somewhere.”
